My comment was meant to be serious although I personally believe that, depending on your age, you might be missing out on the real progress in those fields by just a few decades. As of today your goals are unfortunately in the science fiction territory more than actual science territory. Still, there are plenty of good career options available for you that will scratch that itch while providing a decent living.

Neurology, neuroscience, biotechnology, computer science and programming cover most of what you describe. You should get multiple PhD in these fields.

Best of luck

I've read it translated in my first language and had to read a synopsis afterward to get an idea of what happened in the book. The guy who wrote the synopsis has a PhD in Philosophy and commented it was unclear to him as well what was going on.

Natural selection tends to promote whatever is successful. Either our body adapted around successful sleep/wake cycles or our ancestors figured out the best sleep/wake cycles to respond to their bodies' demands and environmental factors (it's harder to hunt and gather food during the night without a readily available light source).
